Hello everyone.
I'd like to know as much as possible about the spatial audio engine in Houdini, but unfortunately, I really don't know the documentation category it belongs to and, using the search tool, any URL return an error.
Please, will you link relevant documentation link?

To be precise, I saw there are some audio nodes (parametric EQ, oscillator, filter, etc) and almost any refers to this “spatial audio engine”.

Bye, Ivano.

I've never tried this stuff out, but these are the key nodes.

Thanks for the links, I just finished reading all of them, plus audio CHOPS linked at the bottom in the first one.
If I understood well, Houdini supports physical modeling for sound.
Unfortunately there's no much support for synthesis, but judjing from audio nodes popularity I guess no one would use it.

Some day I hope I'm on a project that needs it.
